Move Capture the Flag Competition Recap

This report is a Move/Sui blockchain CTF write-up that walks through four challenges (CheckIn, SimpleGame, FlashLoan, MoveLock), explains the underlying vulnerabilities (predictable/ manipulable randomness, a flash-loan ‘check’ logic flaw, and a matrix-based unlock), and provides detailed analyses and proof-of-concept Move modules and scripts to exploit them and obtain CTF flags.
